Keičiantis klimatui, didėja sausros pavojus, todėl tausus dirvožemio vandens naudojimas tampa aktualiu. Siekiant gerinti vandens telkinių ekologinę būklę turi būti mažinamas upių vandens užterštumas azoto ir fosforo junginiais bei organinėmis medžiagomis. Gerinant vandens telkinių ekologinę būklę, mažinant vandens užterštumą galimas sprendimas yra įprasto drenažo konstrukcijos pertvarkymas į reguliuojamo drenažo sistemas.
The changing climate is threatened with drought and therefore the sustainable use of soil water becomes topical. In order to improve the ecological status of water bodies, pollution of rivers with nitrogen and phosphorus compounds and organic materials must be reduced. Improving the ecological status of water bodies, reducing the water pollution, a possible solution is to reorganize the conventional drainage system into a regulated drainage system. In Lithuania drainage systems, arranged in field arrays, have a one-way operation and are unmanageable. Due to drainage systems (which is associated with diffuse agricultural pollution) and surface water bodies, the protection of surface water bodies is very important in Lithuania. In order to improve the ecological status of water bodies, pollution of rivers with nitrogen and phosphorus compounds and organic materials must be reduced. So one of the possible solutions to reduce the amount of biogenic materials from agricultural areas is the reorganization of the conventional drainage system into a regulated drainage system.
